True Grit

not the movie... but Angela Duckworth did mention it in this talk. I'm really excited about how often she is popping up in my study.

I also found her Grit Test- 12 questions - perhaps I can use some of these for the PGP questions.

Here is a link to Duckworth talking about Dweck's growth mindset as one strategy for helping make kids "grittier"

And finally, the most up-to-date article I have found so far from Duckworth since most of her initial work on grit is from 2007-09. This is from April 2013.
